I''m betting on the clogged fuel line. I had the same engine and the same problem. It''d die, I''d wait, and it would restart, only to die again. I started at the pump to bleed the system, but there wasn''t anything there to bleed. Then, it was only a matter of tracing the fuel lines back to the blockage. Blockage was at the tank, and significant. Once cleared, never had another problem.

Just helps reiforce how important it is to filter your fuel, both at the engine and when you pour it into your tank. I bought one gallon of diesel at a local station and, after sitting for a while, was suprised to see how much debris settled out of just that one gallon!
